Analysis of Control Structures for Reaction/Separation/Recycle Processes with Second-Order Reactions

摘要: This work analyzes the effect of process design on control structure for a system with reactor, two distillation columns, and recycle streams. The reaction A + B → C occurs in since component is assumed to be intermediate boiler, columns components back reactor. previous paper presented workable structures this process. One fixed flow rates streams brought makeup fresh feeds level control. other reactor effluent rate, controlled composition one reactant by manipulating feed, feed These have undesirable feature not being able set directly production rate and, second structure, requiring measurement, which can difficult due hostile environment require expensive in...
